Munich's weaknesses have actually become apparent this season. The 3-goal defeat to Leverkusen was a hard blow for Munich's top brass. In the game, you can really feel the difference in tactics used by the two teams. However, Xabi is a maestro, he plays a fluid strategy where players can change positions quickly to create opportunities which are converted into goals.
The big question is, will Munich try to redeem Xabi's clause from Leverkusen next season? Munich always does this to buy players and even rival coaches so they can dominate the Bundesliga.
Regarding redemption matters such as Xabi's clause from Leverkusen next season, it is still unclear at this time because Bayern Munich itself is definitely focused on reducing the points gap with Bayer Leverkusen, which at this time has become five points after Bayern Munich lost badly at Leverkusen's home ground. However, that doesn't mean that what you say won't come true next season because remember that Bayern Munich is a team that has enough money to bring in the players they want even though they have to go through a fairly well-planned business route.
